Assalamu alaykum people.. I had no idea there was a separate thread for P5... I uploaded this in the chem thread so that everyone gets it.. so here i'm uploading it again for the ones discussing here
May Allah Grant us all Paradise and Success- including the World Distiction(xhizors)

-Pour Water 50cm3 in Plastic cup
-stir a little and measure its temperature (remem 0.2 graduations) its initial temp
-cautiously take NaOH as it is corrosive (use hand gloves as it can react with a moisture in your hand) measure 30cm3 of Naoh using measuring cylinder
-pour alkali in plastic cup stir it with thermometer and record the highest temperature

Thats it no more Rocket science
use equation Q=mc4T => 80gx4.2x(65-30)

Pray for me that i get able to make my way toward a World Distinction Inshallah!!
